Question

So basically I would like to create a function that when alerted, returns the URL from an array (in this case the array is declared as ‘websites’). The function has two parameters ‘websites’ and ‘searchTerm’.

I’m struggling to make the function behave, so that when i type yahoo or google or bing in the searchTerm parameter for the function; I want it to return the corresponding URL.

Any help or support would be greatly appreciated.
Sorry if I have not made myself clear in my explanation, if this is the case, let me know and I will try and be clearer in my explanation.

Thanks in advance!

Here is how:

var websites = ["www.google.com|Google" , "www.yahoo.com|Yahoo" , "www.bing.com|Bing"];

function filterURL(websites,searchTerm) 
{
   for (var i = 0; i < websites.length; i++) {
      if (websites[i].split('|')[1] === searchTerm) {
         return websites[i].split('|')[0];
      }
   }
}

Working Example

You can also validate and improve function:

function filterURL(websites,searchTerm) 
{
   if (typeof websites != 'Array' || ! searchTerm) return false;

   for (var i = 0; i < websites.length; i++) {
      if (websites[i].split('|')[1] === searchTerm) {
         return websites[i].split('|')[0];
      }
   }

   return false;
}
